| + | A '''bullroarer''' or '''turndun''' is an ancient ritual musical instrument and means of communicating over extended distances. [[Image:Music_insts_bullroarers2.jpg|frame|none|Jazz musician Rich Halley plays a bullroarer at an outdoor concert.]] |
| | | | |
| − | Many [[Australian Aboriginal]] cultures have or traditionally had a [[sign language]] counterpart to their spoken language. This appears to be connected with various [[taboo]]s on speech between certain people within the community or at particular times, such as during a mourning period for women or during initiation ceremonies for men - unlike [[indigenous]] sign languages elsewhere which are used as a [[lingua franca]] ([[Plains Indians]] sign language), or due to a high incidence of heriditary deafness in the community ([[Yucatec Maya Sign Language]], [[Adamorobe Sign Language]] and [[Kala Kotok]]).
| + | It consists of a longish piece of [[string|cord]] fixed to an [[oval]] piece of wood or other suitable material which usually is thicker in the center, and sharpish at the edges. |
| | | | |
| − | Sign languages occur in the southern, central, and western desert regions, coastal [[Arnhem Land]], some islands of north coast, the western side of [[Cape York Peninsula]], and on some [[Torres Strait Islands]]. Sign languages may have occurred all over Australia - they have been noted as far south as the south coast (Jaralde Sign Language), but many of these sign languages (as with many of the spoken languages of Australia), are now extinct.
| + | The cord is given a slight initial twist, and the roarer is then waved in a large circle in a horizontal plane. The [[aerodynamics]] of the roarer will keep it spinning about its axis even after the initial twist has unwound. The cord winds fully first in one direction and then the other. |
| | | | |
| − | Reports on the status of deaf members of such Aboriginal communities differ, with some writers lauding the inclusion on [[deaf]] people in mainstream cultural life, while others indicate that deaf people don't learn the sign language and, like other deaf people isolated in hearing cultures, develop a simple system of [[home sign]] to communicate with their immediate family. However, an [[Australian Aborigines|Aboriginal]] and [[Torres Strait Islander]] dialect of [[Auslan]] exists in Far North Queensland (extending from [[Yarrabah, Queensland|Yarrabah]] to [[Cape York]]), which is heavily influenced by the indigenous community sign languages and gestural systems of the region.
| + | It makes a characteristic roaring [[vibrato]] [[sound]] with notable modification from both [[Doppler effect]] and the changing speed of the roarer at different parts of its circuit. [[Image:Music_insts_bullroarers1.jpg |frame|none|Two jazz musicians play flat white bullroarers with red spots held on thin rope lines about eight feet long by spinning them quickly in circles.]] |

| − | Australian indigenous sign languages in north Queensland were noted as early as [[1908]] (Roth). Early research into indigenous sign was done by the American linguist [[La Mont West]], and later, in more depth, by English linguist [[Adam Kendon]].
| + | By modifying the expansiveness of its circuit and the speed given it, the modulation of the sound can be controlled, making the coding of information possible. The low frequency component of the sound travels extremely long distances, especially on the wind. |

| − | ==Linguistics of Aboriginal sign languages==
| + | This instrument has been used by numerous early and traditional cultures in both the northern and southern [[hemisphere]]s but in the popular consciousness it is perhaps best known for its use by [[Australian Aborigine]]s (it is from one of their languages that the name ''turndun'' comes). |

They are used in men's initiation ceremonies and the sound they produced is considered to represent the sound of the [[rainbow serpent|Rainbow Serpent]]. |

A bullroarer or turndun is an ancient ritual musical instrument and means of communicating over extended distances.
It consists of a longish piece of cord fixed to an oval piece of wood or other suitable material which usually is thicker in the center, and sharpish at the edges.
The cord is given a slight initial twist, and the roarer is then waved in a large circle in a horizontal plane. The aerodynamics of the roarer will keep it spinning about its axis even after the initial twist has unwound. The cord winds fully first in one direction and then the other.
It makes a characteristic roaring vibrato sound with notable modification from both Doppler effect and the changing speed of the roarer at different parts of its circuit.
File:Music insts bullroarers1.jpg Two jazz musicians play flat white bullroarers with red spots held on thin rope lines about eight feet long by spinning them quickly in circles.
By modifying the expansiveness of its circuit and the speed given it, the modulation of the sound can be controlled, making the coding of information possible. The low frequency component of the sound travels extremely long distances, especially on the wind.
This instrument has been used by numerous early and traditional cultures in both the northern and southern hemispheres but in the popular consciousness it is perhaps best known for its use by Australian Aborigines (it is from one of their languages that the name turndun comes).
Bullroarers are still considered to be sacred/secret by some Aboriginal tribes and are not allowed to be shown to women, children or outsiders. They are used in men's initiation ceremonies and the sound they produced is considered to represent the sound of the Rainbow Serpent.
The bullroarer is sometimes used as a means of demonstrating the Doppler effect, by using sound. As the instrument travels round, its sound goes up or down according to its speed, and distance from the hearer.
